Features and benefits

TMR triple redundancy safety architecture: three-channel independent sampling, computing, and voting, no single point failure, SIL3 safety level

Core safety logic operations: execute ESD emergency stop, F&G fire and gas interlock, BMS boiler protection, etc. safety programs

Full system diagnosis + hot swapping: real-time diagnosis of CPU, I/O, communication, power failures, supports online replacement, non-stop maintenance

High-speed I/O and SOE: millisecond response, 1ms event sequence recording, meeting accident traceability and compliance requirements

Multi-protocol redundant communication: dual network redundancy, seamless connection to DCS, HMI, upper computer and third-party safety systems

Typical applications

ESD emergency stop system: key process interlocks in chemical, oil and gas, and refining and chemical plants, automatic shutdown in case of over-limit

F&G fire and gas system: processing and alarming interlocks for combustible/toxic gas, flame detection signals

BMS boiler management system: safety monitoring and protection of steam pressure, water level, furnace temperature

SIL3-level safety control: core controller for safety instrument systems in high-risk scenarios such as power, metallurgy, and rail transportation
